How BLIS functions in daylight and darkness

Daylight
BLIS reacts to the shape of surrounding vehicles. The system is designed to help detect motor vehicles such as cars, trucks, buses, motorcycles, etc.
Darkness
BLIS reacts to the headlights of surrounding vehicles. In order to be detected by BLIS, a vehicle in the blind area must have its headlights on. This means, for example, that the system will not detect a trailer without headlights that is being towed behind a car or truck.
WARNING
- BLIS does not react to cyclists or mopeds.
- BLIS does not react to vehicles that are standing still.
- The BLIS cameras have the same limitation as the human eye. In other words, their "vision is impaired" by adverse weather conditions such as heavy snowfall, intense light directly into the camera, dense fog, etc.
